- SECONDARY
- Title
- A Composite Endpoint of Postoperative Infectious Complications at 90 Days Post-randomization: Infectious Complications Will Include Wound Infections, Pneumonia, and Sepsis
- Description
Wound infection will be defined according to the Centers for Disease Control and Prevention (CDC) guidelines as a) positive wound culture, or b) drainage of pus from a wound, or c) suspicion of wound infection that was drained operatively.~Pneumonia will be defined according to the CDC definition as chest radiograph with new or progressive infiltrate, consolidation, cavitation, or pleural effusion and any of the following: new onset of purulent sputum or change in character of sputum, or organism isolated from blood culture, trans-tracheal aspirate, bronchial brushings, or biopsy.~Sepsis will be defined as a combination of two of the following systemic inflammatory response syndrome (SIRS) criteria, plus suspected or present source of infection. SIRS criteria will include the following: temperature greater than 38C, heart rate greater than 90 beats/min, WBC \> 12,000 or \< 4,000, or \> 10% bands.
